Assuming the galaxy in question is the Milky Way Galaxy.
1 light hour like how a light year is how far light travels in a year.
Your question seems to suggest that you think a "light year"is a length of time. It's not.It's a distance ... the distance light travels in a year.The distance is about 5,878,450,000,000 miles.I cannot travel nearly that far in one year.
they travel how far they want to
Mercury is part of our Solar System; our Solar System is part of our galaxy. Look at it this way. Our galaxy - the Milky Way - has a diameter of about 100,000 light-years. We are not precisely in the center of the Milky Way, but everything within the Solar System is within a radius of about 1 light-year - far less in the case of planets in the Solar System (the 1 light-year refers to the Oort Cloud).
At 60mph you will travel a distance of 1 mile in 1 minute.
Light years is actually a measure of distance expressed in time. For example, a galaxy is 1 light year long, which means it will take 1 year to reach that galaxy with the speed of light(c). This implies that the galaxy is c(m/year)*1 meters long.

About 1141 million light-years.
A frequency does not travel. Anywhere, ever.
